Linear Gate Access Control in Southlake: What to Know First
We repair, upgrade, and install Linear gate access control systems throughout Southlake, TX, and most jobs are diagnosed and completed in a single visit. Whether you have a Linear keypad that’s gone dark, a remote that stopped triggering the opener, or a phone entry system that won’t release the gate, we’ll quote the work before we turn a bolt, so you know the full price before anything starts. An independent Linear service provider, Ironworks Gate Co. has serviced Linear systems across Southlake for over 42 years, including the older Multi-Code and AccessBase generations and the newer RE-1 and AE-1000 lines. If your Linear access control is acting up, call (817) 580-8494 and a live person will answer, any hour, any day.
This page is written for Southlake homeowners who own a Linear gate system and want a straight answer about what’s wrong, what it costs, and whether it’s worth fixing. If that’s you, you’re in the right place.
How Linear Products Fail - and How We Fix Them
- Multi-Code keypads losing memory after power flickers. The older Linear Multi-Code 4120 and 3089 keypads used in many Southlake subdivisions store entry codes in volatile memory. One good lightning storm or a power blink off the co-op line, and the codes vanish. Homeowners assume the keypad is fried. It usually isn’t. We re-flash the codes, check the surge protection on the low-voltage side, and add a small inline suppressor where needed. Most of these keypads come right back to life.
- AE-1000 telephone entry systems that dial but won’t release. When an AE-1000 or AE-2000 call box rings the house but the “9” or “#” command won’t open the gate, the culprit is often a mismatched relay configuration or a worn reed switch in the keypad housing. We trace the relay output at the board, not the wire at the gate, which cuts the diagnostic time considerably. We’ve fixed a half-dozen of these in the last year across Southlake and Westlake, and it’s rarely the board itself.
- MegaCode remotes that work intermittently. Linear’s MegaCode series (the MCT-3 and older ACT-31B) uses rolling-code technology, which is good for security but sensitive to frequency drift as the transmitter ages. The symptom is a remote that works from the carport but not from the street. We test the transmitter output with a meter, and if it’s drifted out of spec, we replace the remote rather than the receiver, which saves a few hundred dollars.
- Receivers picking up neighboring gate signals. In tighter Southlake neighborhoods where lots back up to each other, we regularly see older Linear receivers on the 318 MHz frequency opening two different gates. The fix is a receiver upgrade to a model with tighter coding or a switch to the newer RE-1 receiver that pairs cleanly with existing remotes. We’ve untangled several of these on the east side of town near Carroll Senior High.
- Older Linear boards with burned relay contacts. On 15-to-20-year-old systems, the relay that fires the gate motor gets pitted and eventually refuses to close the circuit. The board still powers up, the keypad still beeps, but the gate won’t move. Some companies will sell you a whole new board. We replace the relay itself where the board design allows it, which costs far less and keeps the system running on factory components.
Our Linear Gate Access Control Process
- 1
Call and describe the symptom. You call (817) 580-8494. A live person answers and asks a few direct questions: what the keypad or remote is doing, how old the system is, whether the gate moves at all. You’ll have a service window before we hang up.
- 2
On-site diagnostic at your Southlake property. Our technician arrives, walks the gate and the controller, and tests the access control components with a multimeter before recommending anything. You hear the diagnosis in plain English, and the price before any work starts.
- 3
Parts decision, made with you. Where a genuine Linear OEM part makes sense and is available, we use it. Where a quality aftermarket component is more sensible for an older system (and won’t void any remaining warranty), we tell you why and give you the choice. No hidden aftermarket surprises on the invoice.
- 4
The repair or upgrade. We replace the relay, re-flash the codes, swap the receiver, or install the new access control unit. Our technicians are background-checked and uniformed, and they leave the work area as clean as they found it.
- 5
Test, verify, and explain. We test the gate through no fewer than ten full open-and-close cycles, verify all access devices, and have you run the gate yourself while we watch. Then we explain what was wrong and what we did, and hand you the paperwork for the 90-Day Done Right Promise.
- 6
A written guarantee, every time. Every Ironworks access control job in Southlake includes our 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork, no arguing.
What Linear Gate Access Control Costs in Southlake
Most Linear access control repairs in Southlake fall between $140 and $420, depending on what failed and what we find. A keypad re-flash or relay replacement usually runs $140 to $220. Replacing a worn MegaCode remote or an intermittent receiver typically lands between $180 and $320. Full telephone entry system replacement with a new AE series board and keypad is usually $380 to $550. Complete access control upgrades, where we replace keypads, remotes, and the receiver on an older system, generally range from $600 to $1,100. What moves the price is how much damage the failing component did downstream, whether we’re working with OEM or aftermarket parts, and how much wire has to be rerun from years of neglect. You’ll always get the full price in writing before we begin. Estimates are free, and you can reach a live person at (817) 580-8494 to schedule one, day or night. Our $50 Off Any Repair Over $250 offer applies to most Linear jobs, and we always honor a 5% Senior and Veteran discount on every job.
Why Southlake Homeowners Call Ironworks Gate Co. for Linear Work
We’re a gate company. That’s all we do. We don’t patch drywall, repair air conditioners, or hang ceiling fans. For more than four decades, we’ve worked exclusively on driveway and estate gates, and our technicians are trained specifically on nine gate-automation brands, including Linear, so we’re not reading the manual while you’re paying for the visit. When we run into a Linear system with an uncommon failure, we diagnose it quickly because we’ve seen it before, usually on a gate just a few streets over. And we always carry a backup plan: if a Linear component is no longer made and the system needs to transition, we’re equally certified on LiftMaster, Mighty Mule, Ghost Controls, and DoorKing, so you won’t be left with a dead gate and a shrug. Our work is backed by a written promise and performed by uniformed, background-checked techs. A square deal: upfront price, no surprises on the bill. We will be there when we say. We stand behind it.
Victor Salinas, our owner, grew up near Southlake Town Square back when that stretch of Carroll Avenue was a lot quieter. He learned the fundamentals of metalwork and electrical systems at Tarrant County College’s northwest campus, then spent nearly three decades learning the rest on actual job sites, including plenty of Linear systems that had been misdiagnosed by others. The way Victor sees it, as he’ll tell you: “A gate that works right doesn’t need to announce itself.” That’s the Ironworks standard.
FAQs
No. As an independent Linear service provider, we’re careful to use OEM Linear parts where a system is still under warranty and to perform work that preserves all remaining coverage. For older systems outside the warranty period, we’ll talk through the OEM-versus-aftermarket choice with you before ordering anything, and you decide.
Yes, through a mix of factory channels and trusted aftermarket sources. We keep a limited stock of the common failure parts on our trucks, including Multi-Code keypads, MegaCode remotes, and relay components. Some older Linear boards are no longer in production, and when they’re not, we’ll tell you plainly and present a replacement option rather than patching a dying board. Call (817) 580-8494 and we’ll check availability for your exact model.
For emergency Linear access control failures, we prioritize same-day and next-day service across Southlake, and a live person answers the phone 24/7 to book the call. Non-emergency diagnostics and quotes are typically scheduled within a day or two.
If the board is intact, the keypads and remotes are less than 10 to 12 years old, and the system has never been underwater or struck by lightning, repair is usually the right call. When a system has multiple failing components, a full access control upgrade makes more financial sense than a series of one-off repairs. We’ll give you the numbers for both options and let you decide with the math in front of you.
Yes, estimates are always free. You’ll know the cost of the repair before any work begins, and the price we quote is the price on the invoice. No surprises, no add-ons, no “while we’re at it” charges. Call (817) 580-8494 to get a free estimate, and ask about our $50 Off Any Repair Over $250 offer.
